1. Purpose<\/h2>\n\n\n\n

Clarify the zero-point reference and proximity-sensor logic for forward and reverse rotation of rotary tables.
This document prevents confusion during service and function testing.<\/p>\n\n\n\n

6. Service Notes<\/h2>\n\n\n\n
    \n
  1. Model Identification<\/strong>\n
      \n
    • IMC400 and IMC700\/710 use different rotation logic. Confirm controller version first.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Sensor Reuse Caution<\/strong>\n
        \n
      • For logic-inverted models (VHG5), set sensor ON\/OFF input as reversed.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Software Parameter<\/strong>\n
          \n
        • Do not<\/strong> change the Zero reference within the standard control logic.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • If Zero Mismatch Occurs During Test<\/strong>\n
            \n
          • Check sensor input (IO monitor) \u2192 rotation direction \u2192 controller version in order.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
            \n\n\n\n

            7. Summary<\/h2>\n\n\n\n
              \n
            • VHA\/VHL (IMC400)<\/strong>: Zero = Reverse-rotation complete, Sensor = Completion state<\/li>\n\n\n\n
            • VHG5 (IMC700\/710)<\/strong>: Zero = Forward-rotation complete, Sensor = During rotation
              \u2192 Because the logic is inverted, confirm the model-specific reference before all function tests and service operations.<\/li>\n<\/ul>\n\n\n\n
